When fully operational, it will be the world's largest offshore wind farm - and, as these pictures show, work on the project in the Thames Estuary is moving along at quite a pace.

The wind farm, which is being built in the shallow waters 12 miles off the coasts of Kent and Essex, which, when complete will feature 217 turbines that will be able to supply enough electricity to power a quarter of London's homes.

The 1.7 billion wind farm, known as the London Array, is owned by the utility companies E.ON, Dong Energy and Masdar and is expected to start sending energy to the National Grid next spring.

The first phase of the project will generate 630 megawatts of power - equivalent to a small gas or coal fired power station and enough to supply 470,000 homes.

The second phase will bring the total to 217 turbines, each towering 147 metres above the estuary, giving 1000 mw of power, enough for 750,000 homes.

Work on the project began in January.

It was originally given the go-ahead in May 2009.

At present, the world's largest offshore wind farm is the 102-turbine Walney project, located off the coast of Cumbria.

The Walney project is capable of providing sufficient electricity for about 320,000 homes.

cover the uk in them. far better than having millions of years cleaning up nuclear waste.

In their dreams! How often will the full power output quoted be available? On the other hand they can be sure of collecting vast subsidies from the taxpayer whatever the weather, and leaving us to pay for their ultimate removal.

Where I live they have just taken two of them down as they had broken their sails!!!!!!!. They had'nt been up six months before they were damaged. Thats progress for you!!!!!!!!!!.

- DaB, Cambs,England. - They only require a wind speed of 6 mph or above to generate electricity which is pretty normal for a sea breeze. Personally I always thought tidal or wave power was a better option, especially as the UK is surrounded by water and the oceans are always in motion. Even in the US 50% of Americans live within 50 miles of the coast, yet Maine is the first and only state to bring commercial tidal power online sometime this summer.

I really don't see the problems that people are having with these! 12 MILES OFFSHORE! how is that an eyesore?! someday we are going to have to accept that this is completely innovative and seriously, how is it doing more harm than good?

Will people PLEASE STOP voting for the GREEN party, we get this and they are spoiling our countryside and costing us a fortune doing so.

1.7 million to power 750,000 homes may be if the wind blows. Whats the betting it come out over budget as well. Wind farms are expensive and inefficient. Another factor that they do not mention is what is the expected life span of these wind turbines? In the US a large percentage have proved to have a short life span.

Political Emperor's new clothes. Everyone knows these wind turbines are useless, but the politicians want to 'LOOK' like they are doing the 'right' thing. In the meantime we have to pay huge amounts for this ridiculous eyesore.

Only when the wind is blowing at the right speed. The future - probably the area will be marked for shipping as "Hazardous wrecks".

Great News! floating deep sea wind turbines next please. out of sight therefore no Nimbys complaining or bird strikes. mean wind speed is higher further offshore, so they will produce more energy. new advances in turbine design means they will go from strength to strength. not long now and we can be rid of nasty coal and oil.
